Welcome to the forum,

There are plenty of people on here who will be happy to help you. We hope you find out all you need to know.
There are many threads on here about what to look for when looking at a car, do a search or 2.
Has it been used with WVO? If so turn away & RUN

Does it change smooth without slipping, if it revs up during the change from 3 to 4, there could be a problem.

Any noises or shakes in the suspension? Clunks & shakes can be a sign of future expense.

After it has been test driven, leave the motor running, open the hood & unscrew the oil cap, if it does a dance & wants to jump of it has a blow by problem.

Does the seller have any receipts for work done on it?

What is the history of the car?

Are you going to be doing your own maintenance/repairs?

Hope those few questions provide you with a little focus.

Good Luck with your decision !!!
