Well this is gonna sound weird considering i'm #1 on a list for a USDM STI.
If i had to choose between the weakest STI in the world(uk sti with only 261 hp and 253 torque) or the Tommy evo i would go with the evo hands down. Here are my reasons for saying this: It is 4 model years old so it will cost you ALOT less than the STI. It is just about the baddest evo made. It has an even finer tuned 4G63 engine with a titanium alloy turbo for more power than the STI with a far smoother power delivery than the uk subie 2.0. It is limited edition and LOOKS SOOOO GOOD with or without the exterior graphics. It has an AMAZING RACE INTERIOR made specially for the Makinen edition. This includes special recaro seats, gauges, pedals etc. It has a stiffer, lowered suspension, quicker steering than a normal VI, and optimized roll-center height. It has a specially tuned center-mounted viscous coupling differential. It also has a specially tuned AYC! The car is balls out speed and handling that is mind blowingly somehow street legal. There is more but i can't remember it all. I actually have an english language brochure for the Makinen car but its at work. The only things going against it would be: Only 5 spd gearbox, won't comfortably seat two adults in back seat(who freaking cares), it is used, and it is a mitsu. Now if you get it inspected and trust the seller then the used thing doesn't matter. Especially with only 15,000km(only 9,900 miles) on it. If you are buying this car to haul around 4 people then you are buying the wrong car..so that doesn't matter either. You aren't gonna break any land speed records with the insanely close ratio-ed 5 spd but that isn't the point of this car...so that doesn't really matter either. Mitsubishi isn't #1 for quality...so that is the only real downpoint for this car. But considering it was the crown jewel in their line up and it was a limited production car i don't think you really have much to worry about in that dept. either. So there is my VERY in depth reason to go with the Makinen over the STI. Peace!!
