Recently I drove a 2007 GM (18k) Avis sedan w GPS (38 k inc 60 mo interest) and made comparisons with my scottified panther: the bouldevrad cruiser : basically a 1989 Cp on a 1984 Lincoln Hearse frame w/1991 front quarter (abt 20k over 5 years of operation and 130 k miles)
Most of my driving is long distance interstate to sheepdog trials: 2 or 4 dogs in the wayback, a full trunk (the hollow where the jump seats used to be) a back seat filled with luggage and Ė if Iím lucky Ė a co driver. I will drive from Virginia to west Texas in January.
Cabin: The 2007 is smaller: 2&2 front and back. The driver is as comfortable as the BC, maybe moreso since the 2007 has lumbar adjustments. The passenger has power seat but much less knee room which makes a big difference when co driver is sleeping on a long haul. The BCís cabin seems more luxurious and the contractorís console (aftermarket) is more comfortable and has better cup holders (the 2007ís may already be broken) . more storage (you can drop a notebook computer in it or a 12 pack.. The 2007 has a single electrical out;let Ė not enough for GPS, cell and Ipod (in my case an ibook). Sound: the blauplunkt BC with its equalizer/preamp is better than the 2007. Noise: Scott insists that the low burble of header/dual exhausts is necessary but the 2007 cabin is quieter. Although the overhead had room for (I think) a back up sensor, it must be an option. If the 2007 had one it would be neater than the BC on the A pillar. Instrumenttaiton: the 2007 had a temp gauge and tach and a large (often hard to see) digital speed and s a traditional speedometer. Don;ít know why they didnít go with one or the other. The only time I needed a tach was when I owned a Sunbeam tiger and was concerned about shift points. For my driving a tach is a useless ornament. Iíd rather have the BCís better temp and oil gauge. The BCís Garmin GPS (I bought it for $400 on Ebay two years ago) is more versaitile and visible than Mr Avisí 2007. Apparently neither a GPS nor backup sensor is available on the 2007. Thatís stupid. The BC has both
Performance: I need a punch on the on ramp or when traffic weaving. The 2007n and the BC seemed about the same. The suspensions were Ė without running a gymhaka the same. Scottified BC steering was better than the 2007. The 2007 tranny was smoother than the BCís.
Safety: The 2007 windshield was so slanted the sun wasnít out of it until 11 am. If I owned it Iíd want a sun shield. Driving due south I had the visorr lowered so I had a slit for a windshield. The side mirrors were bigger than the BC but lacked my tiny mirrors that picked up cars in the blind spot. Despite Scottís improvements, the 2007 brakes stopped the 2007 car sooner. The BCís radiator grate should avoid deer damage but the 2007ís airbags are very much better than none on the BC.
Economy: the 2007 got 20 on a trip the Bc would have got 21.3 and should do a little better after Scottís mods.
Cargo: No comparison. The 2007 trunk was probably twice the size as the under the floorboards BC trunk. I could probably fit two dogs and some luggage in the 2007, four dogs and tons of luggage in the BC.
All in all, in the unlikely event someone offered to swap a brand new Grand Marquis for my 89 CP, I'd turn them down.
