if your car has no accessories then its good news because nobody will steal it or parts from it,if you are worried about people breaking inside to hopefully find goods you left inside then i advise getting tints on all the windows and yes i know that under EU law the front windows must have a vlt of 70% window+tint but there are many tints that companies that produce tint light tints.
get the windows tinted,it will not only keep burglars away (no its not like an impenetrable wall but it is harder to snatch things from inside a car if it has tint applied on the windows) but it willl also help reduce the heat and make your car look nicer
.Dont forget to go for good quality tint and i recommend getting atleast a metallized film installed
