I'm not in a hurry and I don't have to get rid of it. Like I said, the car is a rust free southern car. Hasn't even seen a winter. The car just needs a transmission, which I priced from $100 to $300 for a used AOD and priced a full T-5 swap (trans, pedals, etc) for $750. I just don't really have the time to mess with it. It's drives fine till the trans warms up and 1st gear will start slipping. I usually can go on about 10-15 minute drive without it slipping if I drive it easy. It can be test driven with no problems.
I have more pictures and also videos. I can take any picture that's needed. Due to spam I have removed my phone number, please send me a message for anything.
