When we gave a car to our son 7 years ago, I "embellished" it so that he would not feel too entitled about getting a car. For his Ph.D. graduation, we are giving him a model 3. How should I embellish this one, and have fun with it.....??
You can go all out, plenty of accessories floating around on Amazon, Alibaba, Aliexpress, eBay Motors, Tesla aftermarket resellers, Autozone, AdvanceAutoParts, PepBoys, etc. I suggest questionable source aftermarket airbag suspension, extra wide staggered wheels (pulled and rolled fenders a must), slicks with sidewall lettering in white or body colorcode, a large roof rack mounted storage bin to match, tailight and headlight dark smoke tint overlays, complete chrome delete, painted calipers and/or oversized caliper covers, big brake kit, limo tint all around (including windshield) and for a final touch... a mirror finish chrome vinyl wrap in hot pink or heat-sensitive colorshift.
You can pretend you rented a Model 3 or got a loaner Model 3 while yours is out. Then have him drive you to an errand (pick up an ordered pizza for example, key card inside) to reveal the surprise that this is his own Model 3. What a lucky Doctor!
