The bad thing about cars is that they depreciate atleast every 6months due to new plates coming out so theres no point waiting around for a new plate (in most cases cars that are shipped to the dealers are atleast 6months old anyway and some have been found to have rusted underneath before its even been registered) thats why i wouldnt buy a brand new caralso a bad thing about brand new cars is that when u first get it with 0 miles on the clock the cars are generally slow on start up and top end speed, u then have to clock up 20k miles for the engine to fully break in and be at its manufactures specs in according to top speed etc...if your so worried about selling it in the future, just buy a personalised plate suttin like LR59 TVN and sell it with the car on or after 2009, although this may trick most people, the only way u will tell the age of the car is by the log book, however the dvla kinda clocked on to this so they restrict on what is put on the plate
