A big question that hasn't been brought up & I didn't mention. Where do you live & what is driven there? Especially for a first time buy you will need lots of help, advice, & a good parts supply source. It will be tough sledding if you select a brand which isn't popular in your part of the country.
If you live on or near the coast or a huge metropolis, most foreign makes are fairly well represented. However, if you live in the "Heartland," you need to consider what if any "classic" model has enough visibility locally to help with your needs.
A old Chevy or Ford is considered classic in some places & anything "furrin" is considered counter-culture. That isn't nearly as true if you are looking at a newer vehicle but with a $10K budget for car and start-off, you need to be aware.
Remember buying a "classic" anything is a lot like buying a larger boat or an airplane. You will soon discover the initial purchase is far cheaper than the upkeep! Believe me, I know!
