Depends on how much you bought it for and how much you're willing to spend. I bought mine for £12k so not looking to do anything major for a while! Cheap and cheerful mods include stubby aerial, changing the sidelights/interior lights/number plate lights/boot light to LEDs, bonnet dampers, "mad look" eyelids. Invest in some good quality cleaning products too if you're looking to wash it yourself. I picked up a meguiars kit for £25 off eBay and it came with everything I needed as a starter kit. I'm sure a lot of the guys on here will have plenty of options to fulfil your modding dreams
