[DeTomaso] Ferrari 360 maintenance costs-- NPC

[boyd casey]

I always thought a sedan was 4 doors and a two door was a coupe'. The 840
and 850 are cool looking and they attract alot of attention due to their
rareity but they are not really considered "Ultra High Performance" They
have a high top speed ( once you remove the factory limit of 155) . You are
not going to get pressed back in your seat by acceleration.  The 850 csi
(the top of the line) had a published 0 to 60 time of 5.3 seconds ,the 850i
was 6.3 sec and the 840 a pokey 7.4 seconds. If you opt for the 850 csi you
may not be paying Ferrari prices for service but it is by no means an
economy car. the 12 cylinder 380 hp engine was fabricated by the M division
of BMW and everything about it is as expensive as you would imagine. The 840
is a nice daily driver especially if you have a Pantera when you want to get
your adrenalin going. You can drive the 840 on rainy days.
I should also mention that like several other "sporty cars" with back seats
these are pretty much limited to children , amputees, or midgets.
