Welcome! Great pickup and a great price!
Where you should start depends on what you want.
What do you want and what are you thinking about doing?
Since you just got the car I would look into a few things:
1) Check all fluids, replace if you don't know if they have been replaced. (Oil, Transmission, Water/coolant, Clutch, Brake, Power steering)... help me if i missed anything
2) Did the timing belt get replaced after the 100k miles mark? If not, I would look into getting a timing belt and water pump replaced.
3) Look into the paint. Looks nice from the pictures, so if you want to keep it that way maybe have it detailed.
Anything else anyone can input?
