"This applies to a 2006 Cayenne S Titanium Edition. Purchased as a 2 year old CPO from Porsche dealer. Great set of goodies with the Titanium package (xenon headlights, white faced gauges, two tone interior, lighting, side skirts, exhaust tips, etc.) Driving is like a tall sports car, great. Enough room to stow and transport most items, just don't use it like a second home. 18 months of ownership, so far very reliable. Great in snow, make sure you don"t have summer tires on the car though; all seasons will do.
Niggles: engine temperature creeps up when sitting in traffic, but is a known flaw (plastic internal coolant pipes) that should be replaced by dealer while under warranty. Transmission should be better; no problems, but there is lag waiting for upshift or downshift, it seems confused. Have to let the car warm up a bit before it will shift out of first gear when first starting out."
"I bought this certified used 2005 V-6 Cayenne in 2007. Driven by the wife of an MD (according to service records). All services done at the local Porsche dealership. I now have 56,000 miles on it and love it. Quiet on the highway. Ultra stable in sand, mud, snow, and smooth as silk with a heavy load. No squeaks, rattles, or buzzes. Not too big/not too small. Lots of room for 4 large adults on a longer trip. No real problems with anything. Goes through a set of tires every 25,000(ish) miles.
Only negatives - wish I'd bought the V-8 for power as the V-6 is a bit sluggish off of the line. Hates stop-and-go traffic - has a tendency to "buck" when chugging along. At cruising speeds, no problems keeping up (or beating) the pace of traffic. I get 16mpg in city driving and 21-22mpg on the highway. Will run on cheap gas but prefers premium (same gas mileage but better performance with premium). Generally ugly appearance seems to intimidate slower drivers on the road so they get out of your way. Once out of warranty you will want to take it to a non-Porsche shop for service as Porsche charges outrageous prices for parts and labor. I will seriously consider trading this in (down the road) on the new hybrid Cayenne or on a Cayenne GTS. Would love the Cayenne Turbo but prices are rather stiff for that beast."
"2004 S model w/ 32,000 miles. Average 12 mpg/20 mpg road. Bought the 19" tires to start, then for winter I got 18" wheels so I could get the Pirelli Scorpion. Love the performance, quality, hate to put down the back seats. Gladly buy another one. Positive suggestions- auto headlights, easier back seat lowering, go on a diet/solid feeling but could loss some weight to improve performance."
"Having owned only foreign cars, the Porsche Cayenne is my favorite! Grew up with MGBs, MGBGTs, Jags, 2 944s and a 911 with a whaletail! Eventually moved to Mercedes for 18 years. Last year test drove and bought my 2006 Porsche Cayenne. It is black with dark gray interior and it is a 'head stopper.' More people have commented on this car than any other I have owned. I have not had one problem with it. The engineering, finishes are all superb. It is a joy to drive and corners so well you forget you are in an SUV. Just go test drive one and fall in love!"
