I would have to agree on vilero's side with respect to the wagon, and I am trying to cover my bias towards the Lassie TV series. Oftentimes the station wagon models would be separated by seat pattern, so in this case the "E" variant has 3 rows of seats for a total of 9 passenger spaces.

Indeed that seems too much

What about something like this:

I just find that extra information extremely unecessary. And it's mostly vilero who does it. No offense to you vilero, if you read this.

Ambulance was used at first to separate from others, but maybe not so useful indeed. The Four-Door Sedan was used in descriptive name of some cars, no? Especially on older cars.
Even for recent ones, like the Citroën C4, in its hatchback version is officially named "berline" (means "sedan") to differentiate it from the coupé, though that it is not in the model name, so just put as extra info.
For those which did not use it in official brochures etc., it should not be mentioned.

I agree with G-MANN...sometimes I believe that some vehicles on here have too much info. I'm okay with trim names and the official names for certain bodies (ex: Ford uses SuperCab while Chevrolet uses Extended Cab). But I've always noticed that some people use the extra info field to input things such as "Police," "Ambulance," or "Four-Door Sedan." I mean is such info necessary? That's what the class field is for. And those aren't official names for the vehicles.

For those who use Firefox, you can easily override site styles by modifying the usercontent.css file of your profile, and define new rules for styles
(but both of you use IE, if I remember well)

I think having the trim level in italics is a bit pointless and looks somewhat pretentious (it'll look worse for cars with base trim-levels like GLS, LS, L etc. and cheap mickey mouse cars like Daewoos. In fact a lot of trim level lettering is meaningless isn't it?). It looks like you're trying to draw attention to something which may be not anything special. But that's just me.

I vote leave the italics out of the title fields.

I agree with you with that idea, but how about writing extra infos just in non-bold character (the same one used for the Audi's trim levels B5, B6, C5,...), instead of italics (that I don't like too much)?

Yes I have to redesign the database to handle that in a cleaner way, as well as body makers etc.
Putting that in italics was 20 seconds of work, redesigning the database to organize infos in a more clever way is much more work

All Delta 88s of the period were "Royale" (i.e. it is the base trim).... BUT that doesn't mean it still isn't part of the trim, and should be italicised along with "Brougham" and such.
