I wont buy the car in Latvia

I will go with my cousin to Germany. The most important thing for me taht the car is has to be 2-door. Why?? because i am very tall and in 4-door cars my legs hit the steering wheel, because the front seat dosent go that far as it dose in 2door. And 2 thing is economy. About dealers in Latvia, they are just nuts, because almost every car about 1996 cost 2k more the in germany.... And another qestion, do you know a site, about car offers like in mobile.de and autoscaut.de???
