Hi, I'm looking at most likely getting the CTS v sport since the insurance is half the price of a ATS V or Audi s5, Just wanted to ask a few questions. I would like to build it and I know it can make a lot but how's the long term effects does that completely ruin any reliability of the engine? I was planning to eventually build it to 500WHP then stop there. Also how is the handling? I know the ATSV has great handling but for V sport I couldn't find any videos of it being shown off. And there's none at all near me to test drive before I buy it. I'd have to fly to test and buy one.
Mostly that was my own two questions was is it reliable even after upping the power and do they handle well?
Also lastly Im looking at medium mileage options but if I just bought a high mileage with the plan of it dying sooner. Could I just buy a LF4/ ATSV engine to drop in? Is the LF4 decently more reliable due to the rods or doesn't make a big difference?
