Dear Sir, Nissan Sunny is an excellent car. I have been using its 1.3 ltr petrol version since April 2005. It's drive and performance is excellent. Uptill now, no work at all.
Regarding resale value, let me say that the resale of a Nissan Sunny (or any other Japanese car) won't be bad in near future b/c the prices of new locally assembled cars are rising, therefore, affecting the prices of used cars positively (both Japanese and local ones).
