1) People who add body kits, spoilers stuck on with glue and exhausts. Sorry but NOPE adding these things will not make your car any faster but will slow it down due to the weight. Also people who take a BMW 3-series 316i and badge it M3 whilst also leaving the 316i badge there. BMW never did this and also BMW only produced 50 E30 for the UK so trying to pretend your 316 is one of them is the stupiddest thing yet.
2) Boy racers who take say an Astra and think they can modify it to beat an EVO . Sorry but NOPE not gonna happen. If you do shell out enough money to make it happen you could have just bought a better car in the first place. plus to make it happen you will have the most harshest understeering car ever.
3) Adding Kenwood and Alpine Stickers to your car. Firtsly the people who do this mostly dont have a good system anyway, but those that do are advertising it to thiefs. Not a good idea but it does crack me up seeing them broken into and they wonder why them.
4) Mercedes 190E drivers who acually believe their car is fast. Sorry but your car is possibly the slowest car on the road. You forget that Mercedes weigh tonnes more than a Nissan Sunny. You can add all the stupid plastic spoilers and AMG wheels in the world and it will never amounto anything but a slow Mercedes. My suggestion is Barabus but if you bought a 190E you probably dont have enough money for them to do anything anyway.
(N.B. I am well aware that some mercedes are fast cars, i am simply dispelling a myth that ALL mercs are fast.)
