The compact minivan scores points on two fronts: its roomy interior is spacious enough to seat seven adults like a minivan yet its easy maneuverability and smooth handling rides like a compact. Combining the best of both cars, the compact minivan shows promising growth in Japan's otherwise slumping new car market.

Over the last few years, Japan's automotive giants have released a number of compact minivans into the market, including Honda's highly successful MOBILIO in 2001 and Nissan Motor's Cube3 and Toyota Motor's SIENTA, both released in September of 2003. In January of 2004, Honda, to fend off intensifying competition, introduced a redesigned version of the MOBILIO. As fast as they can come off the assembly line, the newest products being offered by today's automotive makers are breathing new life into the market.

○ 7人乗れる

• holds up to 7
• seats up to 7
• accommodates up to 7
• fits up to 7
• has room for 7
• has capacity for 7

○ 取り回し

• handling ease, agile maneuverability (for city driving)
• 取り回しis a purely cultural concept understandable in Japan or some European countries where towns are crowded.

○ 応戦

• fend off (fend off mosquito: almost 'defend') -- 優位の立場から追撃を「振り払う」とい感じ。
• take on the competitors
• fight back (clear & compact or concise expression)
• counter the rivals
• launch a counter attack
• is set to return fire (sounds very military)

Previous minivan models, with their clunky exterior and difficult handling for unskilled drivers didn't live up to consumer expectations while the cramped interior of compacts left large families needing more room.

Take the example of a second generation Gen X mom in her early 30s with two kids: "Including my mother and father I have a family of 6 but the car only seats five so we can't travel all together. But driving around by myself in a big minivan just feels too weird, plus the cost of gas is so exorbitant that it's just a real turnoff." A tremendous business has arisen for manufacturers whose model can meet the needs of this lucrative demographic.

1. A nice word and technically it's OK. But for automobiles words like "bulky" and "clunky" work better in this context.
2. of an 挿入。
3. This is very clever. I think 団塊ジュニャー is translated as second generation boomers. But looking at your paper, I realize that there is no term, at least in American culture, called "second generation boomers". We have baby boomers and Gen X and even Gen Y but no second generation. Therefore, placing this woman as Gen X was most perceptive and showed great insight into the translation.
4. Great word! I wish I had used that!

1. "Too big"; "too small". Yes, these are fine but you are passing up some far better adjectives to describe the vehicles. "Bulky" or "clunky" minivans; "a cramped interior"
2. space 削除。
3. At least in American society, this woman would be Generation X, not Generation Y. Those who fall into the Gen Y category were born between 1981 and 1995 so this woman doesn't fit the category.
4. Read this sentence aloud. It's way too long and you almost lose your breath trying to fit it into one sentence. It would read much better and smoothly as two sentences rather than one. You have translated the quote well and captured the mother's dilemma but it needs to read and sound a bit more natural.
5. a 削除。

1. 近い場所で big を２度使わないほうがよい。
2. baby boomer juniors を Generation X'ers に変更。
3. カンマを追加。
4. Their complaint is を Their complaints are に訂正。
5. 文章全体を Their complaints have paved the way to create a new business. にしてもよい。

1. I am going to be pushy and ask you to find a better way to express this. For example, "unskilled drivers", "those who are not adept at driving", "for those lacking driving skills", etc.
2. Whoa! Where did you come up with this term? Did you mean to say "baby boomers"? Even if so, this woman is not a "baby boomer". If we are translating this for a Western audience, especially an American one, then she would be considered as a "Gen X'er".
3. I wondered about this. Could this be perhaps, her own mother and father she's talking about? If so, wouldn't she just call them Mom and Dad but is using おじいちゃん and おばあちゃん out of respect now that she has children herself?
4. Really good.

○ (2) に関する後日のフォロー：
You had used the term baby busters to describe this generation. Sure enough, this term does exist. Please access the following link:
http://www.answers.com/topic/baby-busters

According to the definition, there seems to be some debate whether baby busters belong to Gen X or not. Based on one definition (born between 1958-1968) the woman in the article would be a bit too young to be considered a baby buster. Also, for what it's worth, "Generation X" generates far more hits than does "baby buster". A search on Google will provide approximately 762,000 hits when entering "baby buster" as the search parameters while a search for "Generation X" comes in at an overwhelming 30,000,000 hits.

So, I would still argue that "Generation X" is the best category to define this woman's generation and is used far more in popular usage than "baby busters".

However, I do want to acknowledge that your use of baby busters was on the right track and does exist.

○ 外形が大き過ぎ
要するに not sleek なので、「過ぎ」に引っ張られて too を使うより bulky や clunky がよい。

monstrosity (of minivan)
tank : Driving a tank around town. Driving my big old tank of a jalopy.
boat : Cadillacのように長い自動車をboatという。
通常vanといえばbusのように大きい。’Drive a van’ is cool!

○ 車内空間が小さ過ぎ

○ 団塊ジュニア
団塊の世代（1946～1964年生まれ）：
第二次世界大戦が終わってお父さんたちが戦地から復員し生産活動が盛んになり、赤ちゃんがたくさん誕生。日本では、特に1947～1949年生まれが大量に定年を迎える時期になって社会問題化。

団塊ジュニア：
普通は団塊世代の子供たちと考える。もしくは団塊世代の後に生まれた人たちで、ジェネレーションＸ（1965～1976年生まれ）と重なる。

ジェネレーションＸ（1960～1970年代）：
この世代は嗜好が多様だから一様なマーケティングが通用しない。x は数学で未知数、Mr. Xは謎の人。管理職から「扱いにくい」存在とされ、「何を考えているかわからない新人類」と呼ばれたことのある人たち。

ジェネレーションＹ：
先日の日経流通新聞によれば、今の大学生の前後の世代で16～25才。両親が戦後生まれで、バブルを体験していない。消費、ライフスタイルの新旗手。この世代を攻略するには同年代の社員を雇うのが一番手っ取り早いかも。

第二次世界大戦直後の大量生産（baby boomers）とその後の落ち込み（baby busters）は史実。ＸやＹは相対概念に過ぎないが、ジェネレーションＸの世代（Gen-X'ers）が原文の趣旨と判断される。

Subtle differences exist between Nissan Motor’s and Toyota Motor’s approach to the compact minivan. Whereas Nissan's Cube3 was developed on model based upon regular compacts, Toyota's SIENTA was designed to perform like a minivan in as small a body as possible. This difference places the focus on developing cars for either better handling or a roomier interior.

Basing their design on compacts, Nissan didn't want their model to wind up as some niche product half-heartedly combining the features of a compact and a minivan. "When the pressure’s on to get the best features of both types into one product, you sometimes wind up with a car that fails to do either very well. If that happens, then you're left with a niche car that appeals to only a small segment of the market. While our compact minivans feature three row seating, they're compacts at their core so drivers can still pull into their garages and parallel park with ease." To ensure sleek styling, Nissan Motor has kept the compact car design intact and boldly entered the compact minivan market.

1. car compactness
2. minivan-compact car hybrid
3. to 挿入。
4. This is a bit awkward. How about, "To ensure sleek styling," or "To ensure an attention-grabbing design," if you are trying to find a way to approach "魅力".
5. on 挿入。

Inomata-san: This is top-notch work. At this point, I recommend that you continue using more challenging vocabulary, idioms, phrases, colloquialisms, etc. There's no harm in trying and it will keep your skills honed.

1. evolves
2. evolved
3. Placing "space" after interior is redundant in this context.

5. This reads rather awkwardly.
6. This sounds too mathematical.
7. They were concerned with the fact that in some cases
8. While technically your usage is correct, I have never seen this expression used in today's standard English. It almost sounds archaic, even though it isn't. We can approach this sentence in a simpler fashion. "…resulted in a niche vehicle that didn't live up to the sum of its parts" or "resulted in a niche vehicle that disappointed in both measures of performance".
9. it → this
10. for 挿入。
11. or parallel parking
12. Almost everyone had trouble with "魅力を確実". How about, "To ensure attractive styling" or even "To present the car in an attractive package".

4. 削除。
5. "Tight parking spaces" and "parallel parking" would be the more natural expressions here.
6. This closing sentence is quite awkward. How do you "live your philosophy to go"? Surprisingly, everyone in the class had great difficulty with 魅力を確実.

○ 車庫入れ
parking
pulling into the garage
backing the car into the garage

縦列駐車
一人を除き、Georgeさんを含む全員が英辞郎にも出ている parallel parking。しかし、これは real estate の豊かなアメリカなどでの diagonal parking や perpendicular parking に対するもの。ここでは車庫入れの手軽さにも触れているから、路肩にたくさん停まっている車と車の隙間を見つけてそこに何とか駐車を、というのが原文の趣旨と思われる。縁石に平行はもちろんだが、狭苦しい 'bumper to bumper' という意味を出すべきではなかろうか。
