If some of these new 700's have the sliding rear doors, be prepared for trouble. I got 4 of them in my fleet last year, new. Out of the 4, 3 so far have had to have rivets reinstalled on both sides of the outer rear. Problem is there is no reinforcement back there. When continual bumping of docks, it is shearing off the factory rivets.
1 car came in late spring(only 9,900 miles) end of day, with gapping holes from the rivets shearing off. I could literally stick my whole arm into the cargo compartment from the outside.
The doors get out of alignment easy, making shutting them harder. I'm afraid it is a bad setup. Not to mention if you have a cold winters, the sliding doors freeze up, not being able to open them. I just don't see this setup lasting 20 years.
An other thing, If some of these cars have the VT-365 international engine in. Be prepared to be in some older cars. 2 of my 4 have been to the dealership for warranty work 6+ times within the 1st year. Seems the engine wants to go into limp mode while going down the road. The only way to correct this is to shut the ignition off, then back on again to reset the ecm codes. As one of the drivers stated, it is a total pain in the arse. Dealer keep replacing parts, but it does it the next day on route again.
There is an awful lot of bugs to be worked out of these new 700's. so take a long hard look before giving up your old car. you might end up back in it from time to time with all the down time on these new ones.
