My personal feelings about these features:
'98 has the newer and lighter air suspension! : Don't care..removed anyway
'98 has upgraded Transmission! : ill give you that..but most mark owners won't be beating on it to the point of failure anyway..a simple jmod and mercon v fluid change will work just fine.
'98 has Clear Lens and HID headlights! : gen 1 HIDs..problem solved
'98 has LED turn signal mirrors! : Don't care.
'98 has Puddlelamps! Don't care...ugly shaped mirrors.
'98 has In-GlassAM/FM antenna! : could be nice if your antenna is busted..mine works great, so not a problem for me.
'98 has Tail pipe cutouts! : so do 95s and 96s
'98 has stylized Chrome exhaust Tips! : same as above.
'98 has Double DIN radio! Same as 95s and 96s
'98 has an extra Third light! : Neon is cool..when it actually works, which most 2nd gens at this age now don't anymore and require fixing.
'98 has OBD-II / EEC-V engine management! : this just means now you have to have it emission tested so no deleting cats, and if it does have a CEL on you will not pass, and there is.no performance difference between OBDI and OBDII..just easier tunability.
'98 has Digital Odometer! : don't care
'98 has Coil-On-Plugs ignition system! : no performance difference.
'98 has the Wood trim! : so do some 94s and all 95-96s
'98 has inside door handles in Chrome! : BFD
'98 has rear seat Center Armrest! : don't care, how often do you sit in the back seat? And 96s have this feature if you want to call it a "feature"
'98 has Tilt and Telescoping steering wheel! : Don't care, just another thing to break, which most have by now unless its either low mile or has been fixed..never had it on a car and don't need it.
'98 has windshield mounted Compass! : really? So what..late 95s do also and all 96s.
'98 has an All-Speed Traction Control! : wish it didn't have traction control at all! Mine doesn't work anyway with the w3z2.
'98 has Point-Down on reverse mirror function! : don't care..again, just something else to break on a 15 year old car.
'98 has Driver Seat Memory Presets! So do all 1st gens..never use it anyway..I'm the only one who drives it.
'98 has Aluminum hood! : way easier to dent..the 1st gen plastic hoods are more durable and really not that heavy.
'98 has a Larger anti-sway bar! : this is a plus, ill give you that..but just find one from a sport Thunderbird/cougar or a super coupe and change it.
'98 has more Steering Ratio (+3.14:1)! : eh I like my stiffer steering..anyway, feels more sporty and less like a boat.
'98 has Illuminated Cruise Control buttons! : so do 95s and 96s..can't say the same for the 93s and 94s but I assume they do also, they are just black buttons opposed to interior color keyed.
No disrespect, just pointing out the flaws of most of those "upgraded" features of the 2nd gens. I'll take a 1st gen any day over a 2nd gen..cheaper, less problems, no emmissions (besides 96s) and more aggressive looks..I like the look of the 2nd gens also but not enough to pay premium price for..since most think they are worth $2000-3000 more.
