I wouldn’t touch that seller with a barge pole. Do a search of their name and read what comes up. We aren’t allowed to mention them as they have threatened the club with legal action. Make of that what you will.
Also, nothing wrong with the auto/tiptronic. They are faster than manuals
E2A
Don’t search their name as it keeps changing. Just search ”High Wycombe“ and see what comes up.
Also look here (http://www.mkivsupra.net/vbb/showthread.php?67644-What-to-check-when-buying-a-Supra) it needs a bit of an update as the cars are getting older but the basics are there. As the one you mentioned is a ‘93 I would want to know what maintenance has been done. Backed up with receipts to prove anything said.
This will also give you a good insight to the cars - http://www.mkivsupra.net/vbb/showthread.php?59334-Supra-Guide-and-Model-Differences-Chart
