Alloys and fog are the main difference. Fog lights can be installed at dealership as well for 10k approximately which won’t void warranty.
Additional items in Oriel are: trunk insulation which can be bought for 4-5k, shark fin antenna and LED headlights. I though have a pre facelift Oriel and bought good LED bulbs to improve lighting
Alloys can be found oem as well in the market for 40k prefacelift, 65k Facelift 16” and 100k for Turbo RS 17” or international RS 17”
And yes tracker drains battery and will also void your warranty if you install. Although immobilizers are relatively safe and insurance/takaful(islamic) is a better option than tracker because tracker can be easily jammed
