MVD Kerala was on a spree in catching mods. How's the things there in tvm now bro?
I don't know the situation about TVM, but suggest avoiding making any such changes, at least for the time being. Seems, they have been checking all over Kerala.
Last week I was coming back from my relative place, en route there was Police checking going on. They stopped me also and then one guy came round the car and finally stopped in left front side of the windshield and looked at the sticker fixed down the corner. Luckily, that was a South India Automobile Association' sticker which he looked and did not say anything..I was worried that TAI sticker affixed to the rear is going to catch his attention but seems he didn't see it or just not bothered it.
I have seen few cars were stopped and parked side of the road and most of them all have visible changes like Bigger rims/tyres, steel bumper guards, etc. Another thing I have seen was that One officer in one hand holding the RC of the car and checking something on his mobile (may be googling?) to see the original colour/fittings of the car?
I am sure that I did not change or upgrade anything other than the headlight bulbs which he may not come to know unless open the headlight assembly and see it and a front and rear parking camera which in any case is not a problem it seems.
Be careful.!
