I originally wanted a bigger, quicker, more grown up car than my mk2 1.4. I was looking at meg 175s, then I found I could insure a 197 for not much more.
i found out the desirable options (recaros, cup chassis, xenons, climate, cup spoiler/rs splitter) and found the r27 came with the recaros and cup chassis as standard (you can only get r27s in ly too) so that helped my search for an awesome spec. All I had to do then was find one with xenons and climate control (and a cup spoiler, or no spoiler so I could fit one).
signs a gear box is about to s**t itself is grinding/crunching over 5k between 3rd and 4th gears.
The recaros need servicing annually (strip, grease and reassemble) or they'll bind together and you might have to cut the pins out (£40 for new ones)
rear brakes freeze on in the cold. So a lot of people leave their cars in gear overnight with the handbrake off.
recaro bolsters are prone to tearing. If they show any signs of wear, you can swap the seat bases over to even it out.
Belts need doing 72k/5years
i originally s**t myself at how stiff the ride was, but you soon get used to it. If you drove while needing a piss, every imperfection in the road was a falcon punch to the bladder.
the flat spot can become annoying (exhausts exaggerate this)
they hold scary speeds (to me anyway) round corners
mismatched tyres make them very tail happy (which is hilarious fun)
conti 3s all round make it very balanced
I did 90 miles a day when I first got it which cost £70 per week
i now do around 20 miles a day which costs around £30 per week
Anything else you need to know just ask
hope that helps
