In the $5k-$10k market, I would be looking very closely at an E46 330 ZHP. I might even try to find a nice, low-ish mileage, E36 M3 with some maintenance records. In that same vein of cars, an Infinity G35 would also fit the bill nicely.
If you don't mind rotary upkeep, the RX-8 is a blast to drive! I've driven the RX-8 a few times and found them more fun to drive than cars like the BRZ/FR-S. Very willing and balanced/capable chassis, combined with a motor that is fun to rev out. I've almost bought one a few times and probably will one day... but beware, gas mileage is horrific, they consume oil by design and the Renesis is known to be, let's say "less than reliable".
In the ~$25k category, I've driven all the main "new" contenders- WRX, Fiesta ST, Focus ST, GTI and BRZ/FR-S. I've even owned a few of them (WRX, Focus ST & GTI). My assessment:
-If you spend a lot of time in the snow, just buy the WRX. I know you have other cars, so I'm assuming that's not the case. Honestly though, the 2015+ WRX is actually pretty good at everything- peppy engine, fairly tight suspension, decent gas mileage, lots of AWD grip and nicer interior than previous versions. It's really a good jack of all trades car that makes a good daily. Before I bought my current daily (MK7 VW Golf R), I owned a 2015 WRX and my wife currently owns a 2016 WRX, if that tells you anything.
-The Focus ST and Fiesta ST are both about as fun as a FWD car can get! The Focus is faster, but the Fiesta is more fun to pitch around. I've owned a Focus ST, good car, fun to drive, great engine, but a bit of wheel hop/torque steer down low. I would recommend it, but I'll be honest- the Fiesta ST is more fun. The FiST is probably one of the most fun FWD cars ever made.
-The GTI is leagues ahead of the WRX/Focus/Fiesta in interior materials, comfort, refinement, etc and is still fun to drive. Me personally, if RWD isn't a priority, for a daily, I would likely be leaning towards a MK7 GTI w/Performance Pack. That's a lot of car for the money and a great drive.
-BRZ/FR-S: if you're on a great back road, or drive in the canyons a lot, these can be really fun cars; but for the daily grind/traffic, I didn't come away terribly impressed. At my elevation (5200 ft), the last BRZ I drove felt pretty anemic. The chassis has great balance and steering feedback is pretty good for a modern car with electric steering; but in order to exploit it, you're going to want some open, twisty roads. Light to light, I felt it was a bit on the boring side. For a daily that sees lots of traffic, I would prefer one of the above mentioned boost buggies.
Honestly, I think you should do 2 things:
-
Assess your budget and decide how much you really want to spend. There's a big gap between $5k-$10k vs $25k. Do you want to take on a car payment? Do you mind performing deferred maintenance on an older car? Do you want a warranty? Will you have to depend on this car daily? Things I would get in order before I went shopping.
-
Get out there and start driving cars. I might prefer apples and whereas you might prefer oranges. Only way to know if you like something is to drive it for yourself. So, get out there and start driving!
