They weigh over 4,000Lbs so they already don't match. Manuals were insanely hard to find and only came in the V6 SC cars so a V8/stick probably won't happen. They rust. Did I mention how heavy they are?
If you are serious about RWD/V8/Manual I'd look into F-bodies. The prices are dropping insanely fast with the "new Camaro" out. Super clean LT1/6-Speeds are getting $3500, LS1's for $5500. Your pick, WS6/Trans Am or Z28/SS.
