Yep just to add upon what others have said, it's all about growing up and having more financal constriants.
I spunked alot of money on my mini cooper when i was 17 and paid for it through my part time jobs but the feeling of turning up to a show was imense and was a great 2 years.
Fast forward 5 years i really dont want to do that much to my clio i bought it cause i knew little to nothing had to be done. I know in less than a year (hopefully) i'll be paying for a morgage etc so i cant or dont want to be able to afford the insurance that comes with modding.
The only thing that would be nice, would be a set of Recaro Sportline Cs seats and new (high end'ish) components for the front.
Clios look great lowered on coilovers but as someone said you need to set them up so you've got 500 quid on product and 300 (probably) on setting up thats alot for a lower look, thats if you want to do it properly and dont want to comprimise on the already very good handling of the 182.
I always think if i was to pop off the surface of the earth tommorow would i still regret any of the things i've done or purchases i've bought and as long as i still can say no, im happy, lifes unpredictable, do what you enjoy now so you dont miss out later.... (actually if the things that make you most happy, financally cripple you dont do it, you'll end up not driving the car because that 350 quid on I/k cant be spent now on petrol)
