Actually I also had a dilemma like you last time..
I drove a Perdana V6TT (my favourite like you waited for 9 years but lucky price for perdana drop) before but for a year after used I sell the car off since once I calculate the maintenance and the time lost for this, I can buy a brand new car with no worries for another 5 years which I am using the car now...hehe...
Every time sit at garage just to wait for the repair, service, and upgrading until one time my gf (now wife) ask me to marry the car instead of her.
It will be like having a pet or mistress once you own such monster thus pocket always dry, want to go here need to think and calculate, go there also calculate on the budget.
Manual also will make your life miserable since you are in Klang valley thus you can not able to guarantee that your butt will stick in office for another 5 years since such market situations.
The FC, no need to think it will be low since mine full tank just can reach 350km (since modded a lot) only i dont know how many liter tank (5 year back already) but damn can easily reach RM 1000 just for petrol a month coz every tank RM 100++
Just my experience, at the end also depends on you...
me now just an a pek sitting a family car with kids now..
every one also want to owe their dream car, make sure that car is a liability not an asset.
Good Luck
