Bold entry Joebio! Jump in, get Roscoe wound up, ballsy

I think you will fit in just fine. Now we just need to hook you up with Evan
I to started out in your price range and then found out that by the time I got the car the way I wanted it I was way over 40. Check out the used market.
Another Unique plug...... If you are concerned with the used part bit and want the IRS.......... look at Unique. Rock bottom dollar to finish one with all new parts and a 'buy the beer paint job is going to be in the 37+ neighborhood. I have seen many finished cars from Unique that exceed 50. Getting a car done in the mid 20s will virtually guarentee donor parts and a solid rear axle. I am sure that there are exceptions but I would expect them to be few and far in between.
I don't know about your car skills but while these cars may be refered to as 'kits' they are nothing like 'nut A on bolt B'. To get a nicely finished good running car takes a lot more than being able to follow instructions. Please keep that in mind when you select a manufacturer.
Have fun (and watch your back
