Since you wanted a somewhat smaller faster vehicle, I figured this Sedan (Which looks like you might find it on a race track by the way) was a good pick. Good body and armor for when you get shot at, and not overy expensive. Also the body will let you mod it quite a bit (Funds allowing) and the handling will help you keep it on the road.
Some mods that may be particularly handy for you:
(Note, you have 10 slots, and I'm listing the prices based on a body of 10, some have variable prices based on body, but I figure I won't post the entire book on the forums)
Anti-Theft system, 2 slots, 2000

<- Zaps people trying to steal your ride for 10S electric damage.
Chameleon Coating, 2 slots, 10000

<- A chameleon suit for your car.
Engine Customization(speed), 2 slots, 9000

<- Increases speed by 20% (Making it faster than anything else stock)
Engine Customization(Acceleration), 2 slots, 5000

<- Increases accel by 20% (It is already one of the highest accel vehicles, but this really makes it tear away)
Enhanced Image Screens, 1 slot, 1000

<- Can make your car look full when it is empty and empty when it is full. (When looking from outside the car of course.)
Fuzzy Logic, 1 slot, 2500

<- Pilot can spend a complex action to add +2 to a test of its choice (Needs minimum 3 pilot, good if you want it to drive itself sometimes)
Lock-On countermeasures, 1 slot, 5000

<- Chaff and all kinds of other stuff to help against being targeted for the big stuff.
Nitrous Injection, 1 slot, 2500

<- +20% accel in 1 combat turn bursts for up to 6(Then needs refuling). Continuous use is dangerous for your car, but can be great for when you really need to peel away.
Oil Slick Sprayer, 1 slot, 500

<- You -know- you want one. Six charges at a time, +2 threshold to crash tests for people who run through it.
Off-Road Suspension, 1 slot, 4250

<- +1 handling offroad, -1 handling on road (Off-road tires do the same thing for 400 per tire as well as running flat.) This might be handy if you'll be off-roading alot.
Rigger Adaptation, 1 slot, 2500 <- You'll need this if you want to rig your car.
Road Strip Ejector, 1 slot, 800 + price of strips <- I'm sure you can guess what these do.
Smoke Projector, 1 slot, 700 <- Once again fairly self explanatory.
Smuggling Compartment, 1 slot, 1500 <- Basically the whole point of the car, this lets you get the small but high value stuff through without much worry. Can get various shieldings for it (Airtight, lead lined, etc) for 3000ish each.
Turbocharger, 1 slot, 9000 <- Can be taken up to 4 times, each time gives you +5/+10 accel.
Weapon mounts <- Highly varriable and alot of rules for them. You'll want internal or concealed mounts, which will cost you alot of your slots.
So, here is a list of some mods that I thought would be useful for you and the basic rules for using them. You can pick and choose based on what you think will be most useful and based on how much you want to spend on the car.
Good luck in your game.
