I don't know. On any given day/mood I like different things. The Pajero Sport I have now is turning out to be a really good car. For anyone in the market for a 7 seat SUV, the Pajero Sport and the Fortuner come in at about 1,900 kilos. The Isuzu MU-7 is a whopping 3,000 kilos. It is a tank and assume it runs that way on it's 3.0 diesel turbo. It must be very fuel thirsty. It's bigger also with a lot more room in the 3rd row. It's at the point IMO where you'll have problems with city driving/parking here. The Ford Everest is becoming more popular, you see many around now. It has plenty of power and not bad looks but I hope they get rid of that swing away spare tire on the back. Just added length to bump into things with. It also badly needs an electric drivers seat. Even a western size adult feels like you're sitting in a bucket. Too low and my eyes roll at their R&D people not realizing Thais are short people and perhaps their sales would go up if they offered an electric seat.

The only Ford that has one to my knowledge is the Focus. The Chevy Captiva is a good SUV also, on par or better than the Honda CRV. See more and more Captivas these days also.
Sedans, Honda is offering their nifty Accord V-6 3.5 liter again. Runs on 3-4 or 6 cylinders depending upon how you are accelerating/cruising. Not enough for the government to give it a tax break though and it comes in just a tad under 3 million. So basically you're spending $100,000 on a car valued in the USA around $30,000
The Nissan Teana is a nice sedan. Standard is a 2.6 V-6 with plenty of grunt, but under the horsepower/displacement limit and gets the government tax break. Line up a 2.4, 4 cylinder Camery or Accord against the Teana for a quarter mile and I think the Teana wins by several car lengths.The Teana also has that special continuous variable transmission exclusive to Nissan.
As we know though fancy sedans here, including BMW, Mercedes et al, are more status symbol than useful, practical transportation. Where is there a highway to run at 120K + for hours on end?
Most practical for the bump and grind driving most do in this country is still a pick up or SUV, with the small 'city' type sedans for anyone who never gets out of Bangkok or similar. Pete
EDIT: Forgot...ticked Honda above only because of their service. Better than Toyota IMO and Mitsu service is almost non-existent. Their dealers are in the dark ages. Ford and Chevy try harder, but often have mechanics playing cards due to lack of work volume.
