I bought my GTT for 26k, well I borrowed 10k off the old man.. But you get m'drift...
You can find GTT's for around 20k if you look hard enough, but personally, I wouldn't advise getting anything that is any cheaper... yet..
However I got a 4 door, turbo manual which is a bit rare, if your going a turbo manual coupé, or a turbo auto taxi, then things get a bit cheaper...
Hot 4's are selling their project car on Ebay, it is an absolute steal atm..
