Edit just read $10k max...
I'm looking for something that can pass slow cars quickly on hilly curvy roads with limited passing opportunities.
30 mpg highway or better
STEALTH...low profile so police won't follow everywhere
reliable...I don't want to forever be bringing back to the mechanic
affordable...less than 10K total
40 mph to 80 mph passing is what I want it to excel at
Handling is not a high priority as this is going to be a highway bruiser and not a race car
Cars I'm considering:
SAAB 9-3 (late '90's to early 2000's) with mods
PT Cruiser Turbo (manual) with mods
Chevy HHR SS (turbo, manual) with mods
Are there any others I should consider?
Are there any reasons I should eliminate some from my list?
Looking for some wisdom from TCL sages.
Wont hit your mpg and hp goal from the get-go, but maybe consider a pontiac gtp. Stealth, pretty cushy, reliable, and good response to mods with solid aftermarket support. Plus, roots blowers are nifty.
'86 Jaguar xj-s 5.3HE coupe, cobalt blue metallic/blue
'08 Hyundai Accent SE hatch, ice blue/gray
Bisixually disposed, lucas charged and coventry clothed
These ($10k) will be more likely around 260-280hp but should provide good passing and "fly under the radar". Otherwise some older sports car with really high mileage. Assuming you must have MT, the last accord V6 sedan was quite the Q ship and should fit into your price range. In silver (or god forbid beige) it will blend in better than just about everything mentioned so far.
Another vote for the Regal GS, GTP or anything else with an L67, in your price range you could even get a newer GTP with the series iii motor which made a little more power but a series ii with a 3.4 pulley and supporting mods will make the same or more power.
