Stick with it mate, in my first T Sport I had a very similar prang - new wing, new bumper and headlight was required. The car sat in the drive for around a month until I sourced the parts and once it was all repaired, instantly feel back in love with it, It was only when I got a "soccer" scholarship in the states I gave up my first Celica.
After coming back to the UK and driving a host of different cars, Astra SRI, BMW 320D, BMW 318i and a Clio.....I took the plunge and found myself a Storm Blue T Sport that I just couldn't resist.
Not only that, this site is by far thee best community I have ever known, and if something happens with your car, you know someone here will be able to help you (AMS in particular for you).
A said, give it time, slowly build on it, do your brake upgrade (I plan to do the big brake conversion) maybe add some skirts, GT lip if you have a new facelift bumper and you will no doubt find your love again ! Although when I got mine repaired, I went for a pre facelift bumper and dynamic lip - I preferred this look as it was a little different from the rest.
PS your line about buying the mrs new clothes when you get bored of her made my day!
