1. u dnt need to be 18 to get your license, that roumer comes round every year for people about to turn 17
2. u can do your driving test at 16 if you have certain disabilities, my m8 has to wear them metal things on his legs like forest gump, only needs to sleep in them but it made him able to do his test at 16
car wise, all that **** about insurance is a load of balls. dont go for a corsa or sum crappy 106 or saxo, your bound to have high insurance on them because of the ammount of accidents people have in them because they normally young drivers and just thrash them about.
myself i go for the type of cars older people drive, was looking for a volvo s60 t5 the other week, priced my insurance up at £1500, then tried my insurance on a ford KA and it was £1300. Now im not being funny id rather pay the extra £200 on my insurance and have a good car then sum ****ty ford KA.
all i can say is try your insurance on loads of different cars, just been n got a rover 75 2.0 v6 love the interior n the insurance on it for me is cheaper then a 1.1 corsa.
another tip for your insurance, have you as the policy holder and add 2 women who have been driving for 10+ years and have had no crashes or claims within 5years. this tends to drop my insurance alot.
doesnt matter who the women are, could add the queen if u wished, its not illegal to insure sum1 on your car on your policy.
wouldnt add the queen though due to the job type may up the insurance from stalkers + assassination attempts that may be made to the car lol
good luck, post office insurance seems to be cheap lately, but keep checking about as insurance goes up n down all the time
edit: like skyline said though, get a cheap car (like £600ish tops) for your first car, so your not worried bowt bumping it etc., you learn to drive AFTER your test. just dont aim ur cars at corsas/clios n stuff because ur afraid of the insurance. u wont know unless u try it. thers a rover 75 1.8 on autotrader for £600 atm, be a rly nice first car n its cheap, the engine isnt very reliable though iv heard the 1.8 is rubbish whereas the 2.0v6 and 2.5v6 are tanks
