eBay
With an extremely heavy heart I do this, it seems I have come to the end of the road now, and circumstances in life bring along this opportunity for someone else to take over and to own one of the best if not the best Honda Civic SiR (EF9) in the UK, if not Europe. 
I have owned this car for almost 8 years and it was a dream to own one since I was very young. When the time came, myself and a close friend helped me import it. After that I have been through a bit of a journey with the car bringing it to what it is today. At the moment it's a very expensive garage ornament and very rarely gets driven, just look at how many miles its done over the past 5 years. I have a 120 page build up thread of this car over on the 4th generation civic forum (4guk . co . uk), when it was first imported and all the changes it went through over the year, and they are a lot. It's worth a read if you have some time, if not, the spec is listed below.

A few niggles include:

Slight crunch into 3rd gear, ONLY when changing from redline in 2nd
Exhaust sometimes vibrates against ARB, stiffer exhaust rubbers will sort this and I aim to have this sorted before sale
It was painted about 5 years ago and although the paintwork is like glass, there are a couple of nicks in the paint, I could probably count these on one hand.

Apart from that it's in astonishingly good condition for a 25 year old Civic and it makes my 5 year old Audi look very inferior. It is rather low and it handles very well, I take it for the odd blast up over the moors and with 170hp (ish) it is still so much fun, it has solid mounts and solid bushes so apart from the vibrating it is a very nice little car to drive. The car is in my name, logbook is in my name.
