The prob is not how the car is designed or how it looks but is the brand that makes ppl think its uncle car. If u look at s'pore car population, and see Sunny, Latio and Cefiro how many uncle vs youngster u can spot drivin tis few models?
Out of 10 i tink oni 2 are drivers aged below 35 yrs old.
(We tok abt jap brands) --> just take a look at eg. Lancer, Colt, Civic, Fit, Swift and Vios, 7 out of 10 belongs to a younger crowd.
Face the fact, like wat i said unless ur nissan is a fairlady, silvia, GTR or skyline no matter how much mods u do ppl will still generalize our ride as an UnClE car.
