good low mileage but thats a kinda high price. Especially since there seem to be gaps in the front fender and the hood. There may have been a front collision. I would talk him down.
You need bigger rims, bigger tires would do you no good. Look at the integra pic thread and see, people with lowered tegs usually have bigger rims and it looks great. You will need new tires with the rims as well but you will want low profiles as well.
