I just skimmed the links real quick and they all seemed decent, but I didn't bother to read the descriptions. (The first one looks clean)
Before posting 10 different links, you have to make up your mind and decide if you want a 350/auto or 305/M5. Do not get a 305/auto you will outgrow it in a month.
If you are going to drag more I'd suggest a 350/auto, you have a better platform and 700r4's can be built tough. If the manual is more yout thing than a 305/M5 is the way to go, it'll be slow but fun. (Throw some Aluminum L98 heads on there and you'll $H!Tstomp on that 350). It's important to know what you want because there is a big difference between the two...and You'll have people talk a lot of crap because it's a 305 but atleast you have a manual, or people talk crap because it's an auto with the 350. You can't win with these cars, only the fox body can you do that.
Or you can get a very cheap 'bird, something with a v8 atleast and just have it to see if you will like it. I had my Camaro and T/A at the sametime and both are different. I enjoyed the T/A more from an exterior and interior point-of view. I liked the interior 10x more in my GTA than my Z28, it felt much more racey and oldschool imo. The Z28 felt like a it was trapped transitioning into the 90s or something.
But my biggest piece of advice is wait until you find the right one, I did some impulse buying and look where it took me, from 1 nice car to 2 mediocre cars, to zero. If I waited I would of had one badass ride but now I'm waiting to get my bike license and driving a Geo tracker, it was still good lessons learned about the Camaro and the T/A however.
All original except spoiler and seats? DROOL!
EDITx2: Car isn't all original under the bay, still looks good. Ask why it needed repainted. White on tan is sexy though.
