Best in game cash car?

I would like to know which is the best top 5 current IGC?
Please state your cars and reason of your car list. Thanks

I suggest buying Ford Mustang Boss 302 (2012)

i suggest you buying lamborghini lp650 because now its very fast car in igc.

i think u should buy an lp650 leorina ..because it has a fast acceleration ( i tried the car) and same handling as lp640 ....the nos seems more effective on the lp650 than on the lp640 ....hope i helped ....second suggestion is the LFA ..it is more stable than Boss ..but does not have cosmic nos (neither the boss)

SO :
1. lp650
2. LFA
3. Boss '12'
4. Evora ( good acc and cosmic nos)
5. Europa or M6

if u want to beat an MR2 ..u can buy a solstice GXP ...nearly same performance....hope i helped

BMW should be the best too
