As the title says. I’m 50-50.
Car 1:
I picked up an awesome deal on a loaded 2013 C63 - all the goodies including the forged motor, LSD, brakes, speed limit. I took over a lease with $900 payments and a buyout of $33K CDN in less than a year. I can drive another 50K km in the next year on the lease, it still has warranty. Stock except for 245/275 rubber on the stock 19s.
This was the car I was intending to keep - until a sweet old lady forced me off the road last month and caused $17K in damage - replacing most of the front suspension and subframe. Not sure if I want to buy it back now.
Car 2:
The S4 is a DSG, Prestige w/ADS and sport diff. It’s been stock for the last little while, but I have an arsenal of parts either been removed from it’s previous incarnation, or never been installed:
Brembo GT 380mm BBK
APR stage II w/pulley, fully loaded ECU w/4 tunes
JHM stage II crank pulley
Roc-Euro intake
EC sways and adjustable end links
Adjustable upper control arms
RE-11s
Mrs Spazz is currently driving the S4, but will trade for an SUV - how typical lol.
Car has 100K km - the motor has 50K km
I have another track car, but I’d rather use one of these two in the next year for daily (120km) and track duty. I go once a month.
If I keep the C63, it’s getting COs, sways, track alignment, long tubes, upgraded oil and trans cooler, sticky track buns, and maybe a tune. I like the V8 a LOT.
If I keep the S4, it’s getting all those parts plus a track alignment, maybe an exhaust too.
SO. what would you do. vote!

You are welcome to try it out if you like. By the sounds of all the tracks you go to, we shouldn’t be far from each other. PM me if you’d like to give it a whirl.
