It depends on the market of the new ones. If the new ones are selling $45-50K and stay there (which they are right now) it will make for a higher used car cost. If you look at the Disco, LR was pumping $5,000 per car in trunk money for us to dump the '04's on top of Service Loaner money, etc. All said and done you could get a car with 2500 miles with new car financing for THOUSANDS under MSRP.
On the LR3's we have no incentive money, there is a $1,000 owner loyalty incentive, and there was a sales challenge a couple months ago that (if the dealer hit their objectives) amounted to $750-1,000 per LR3 SE sold during the month but that's gone. I imagine LR will give us something like $2,000 "alternative finance incentive" i.e. not using the 3.9% or the lease support. But with no support other than strong leases and finance rates every dealer in the country is selling them extremely well. Even if they do that to blow out the last 2005's in a few months, they are all selling over $40k.
I think it will be slightly stronger than the Disco. Look at the cost of a 2003 Range Rover, or a 2003 SL500, much higher than a 2002 (old body style) model of either car. I would say in a year you could pick up an SE with high mileage in the upper $30k's but probably another year after that before they drop below $35k.
I like the idea of a V6 engine for fuel economy, and for choice if you like it but really don't need a V8, but the price is only $3,000 different when you get a V6 with the sunroofs and stuff. Shit, it's $13,000 to get a supercharger on the RR engine, I was expecting more of savings by downgrading to the V6.
