That is one tidy looking car .. (ignoring the exhaust and the cracked wing, which I assume is now fixed ?)
Just some friendly advice...
Leave it standard, save your cash, keep it mint and buy something else in a year or so when you've got some NCB behind you.
If you're having to save up to buy a new exhaust, how are you going afford the rest of it, or the insurance hike when you put all that on ?
Bearing in mind you can can buy a 'real' 172 for £1500 or less, by the time you've done all that, you'll have a car you find near impossible to sell on, have spent a fortune, and 172's will be almost free...
Just enjoy it, don't become another statistic (we'll zoom past your Skoda incident

), and upgrade when the time comes later on !
