a dci 80 you are looking at atleast £1600 on your own insurance, dci 65 about £1450, your cheaper insuring a 1.2 from my experience. and that depending on your spec can be more a dynamique os £70 more than an authentique
at the moment you will not get touched with a 10 foot barge pole, unless it is to ram it up you sphinkter. for mods fast car, do insurance through fluxand will insure anythign legal, but they will want £4000 plus a blow job for every one in the office twice a week over the course of the premium.
i got quoted £1500 for a s reg 1.1 saxo when i passed at 19, went insured under my dad for £400, but that comes with alor of risks Most places if they find out you have been the main driver they will not pay out.
also expect an excess of atleast £250 mandatory, most places whack an extra 250 minimun on you voluntary excess for being under 21 and about 150 for being under 21-25. tesco have a set £400 excess, so i have no voluntary, Norwich union simple plan give mt he the cheapest quotes however have a mandatory £375 excess and a £250 under 21 excess (total if you crash £625!)
tesco worked out cheapest for me in my 1.2 clio, but for others they have been expensive.
to be honest i'd wory about the next year of getting the license, you know the teory test, hazard perception, the crash courses arent really worth the money from friends experience, then lower your abishions, no remapp, (i know 120 odd BHP sound tempting but for a young driver it could kill you or loose your your license quickly), no exhaust no alloys, get a nice 995cc hairdryer, and run that till it dies, or get a really well paying part time job.
