well this is the issue w/ your opinion... the suburban is a hot car don't get me wrong, the intereior + paint is off the chain i gave him 9/10 on both (i don't give 10)... now lets talk about motor

ya 2/10 and thats b/c i was being generous giving him points for the 20$ air filter.
when you score so low in a category a car/truck like Toms lighting is going to win. he has too many points spread out throughout his score sheet.
even jonathan chases truck w/ the 38 color paintjob which has far better paint then the suburban has no ICE so he got 0/10 in that category... its hard to make up 10 extra points.
now here is something else both the s10/suburban lost on... Display points... there is a category for BONUS both trucks got 2+ points for paint being so extreme but tom's truck got like 6+ points... he had a full display listing of items on the truck w/ the truck covered by a tent and there are tons of prototype 1 of a kind pieces on that truck.
all three trucks were hot and actually the points totals went like this:
Tom lighting - 51/70
Jim suburban - 49/70
Scott 350z - 48/70
Johnathan s10 - 46/70
the top 4 were all 1-2 points of each other. when we are talking big money you can't expect it to just be giving away you have to earn it. every single vehicle listed has been shot for a magazine, so there was no BS in the judging
ps. the hottest ride there was the white lowrider w/ custom paintjob... i've seen everything else before many times but that ride was fuck sick and clean.
