Ok Here's the deal. I live in San Antonio and the only subaru dealer here, as you all prob know is, North park Subaru. I bought my first WRX from them back in 2002 because my Dad knows Ancira and he referred us to them because they would give us a good deal on a WRX. Well I traded in my WRX for a 350Z a while ago and then traded that in 1 month later for a Nissan XTerra ES. Now I want a STi b/c I have saved up for it.The thing is North Park is offering me any STi with $1,000+ off any one I choose. BUT they are only wanting to give me $16,000 for the Xterra. I know you always lose in trade in's but that is way too low. Even though I had all the Mod's on my subaru World Car Nissan still gave me like $18,000 on it and it had like 15,000 miles on it. The Xterra is only 4 months old and has 3,000 miles on it. I have heard bad things about the Subaru dealership here in San Antonio so I was planning on looking at the dealerships in Austin, Dallas and so on. Thing is who Would you guy's who maybe have bought from them suggest me to talk for the best deal. Or hopefully there is a car dealer here from one of the dealerships that could help me out? I would REALLY appreciate it. Thanks.
